8 Claims.

This invention relates to curtain suspension mechanism of the traverse rod type and more particularly to idler carriers and master carriers employed therein.

Conventional traverse curtain suspension arrangements generally employ hollow C-sectioned curtain rods mounted across the top of a window or door frame either in single rods of measured length or with two such rods in telescoping relation. The slot formed by the opening of the c section is faced to the rear toward the supporting frame and curtain carriers are provided in the slot to support the curtain in sliding relation to the rod. When two curtains are mounted with drawstrings to open and close them, master carriers are employed to support and overlap their adjacent inner edges and the drawstrings communicate through the rod to the master carriers. Idler carriers to each side of the master carriers support the remaining areas of the curtains.

It is an object of my invention to provide a simple, light-weight, noiseless, and inexpensive construction for carriers in which the retaining member will not interfere with curtain drawstrings, and in which the weight-supporting elements will be adapted for smooth sliding along the rod.

Another object oi my invention is to provide a one-piece, stamped metal construction for idler carriers and master carriers which will be solid in construction, which will not require an assembly operation after formation of its elements, and which will not tend to come apart after extended use.

In the accomplishment of these and other objects of my invention, I employ a master carrier and an idler carrier formed from sheet metal and die stamped to provide inwardly extending rounded weight-supporting projections and rounded retaining members on the said projections.

It is a feature of the carrier of my invention that it is a single piece, metal stamping in which there are two partly rounded shank portions, one

of which is the weight-supporting member and both of which are provided with rounded retain ing elements for holding the carrier in the curtain rod slot. These elements may be readily formed from a single piece of sheet metal by conventional stamping operations. Furthermore, as formed, they present rounded surfaces to the weight-bearing edge of the curtain rod slot and for that reason slide smoothly and noiselessly thereon. A further advantage of this construction is that the joint between the rounded shank and the base plate from which it is formed is curved and thus forms an essentially rigid connection as will be explained more in detail below.

It is an additional feature of my invention that the retaining elements are in vertically spaced relationship with a gap between them. thereby providing more space for the drawstrings and minimizing interference between the retaining elements of the carrier and the drawstrings.

There are two types of master carrier of my invention. Both have the same main body but one is adapted with an overlap arm to bypass the other and carry the inner edges of adjacent curtains into overlapping relationship. In addition to the features mentioned above, the master carrier of my invention is provided with inwardly bent, ski-shaped runners which facilitate passage of the carrier over the projection of the inner of two telescoping curtain rods.

Further objects and features of my invention can be best understood and appreciated from a detailed description of al preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which:

In describing the preferred embodiment of my invention herein shown, I will rst describe the idler carrier shown in Figs. 3-5, and thereafter describe the master carriers shown in Figs. 6-12.

The idler carrier herein shown comprises a base plate I preferably of sheet steel with a perforation I2 in its lower section adapted to receive a curtain supporting hook. Along the upper sides of the plate II), two flanges I4 are bent to the rear, normal to the plane of the plate I0. These flanges I4 serve both to provide longitudinal rigidity to the plate and to prevent the carriers from wedging under each other in locked relation while sliding together in the slot of a curtain rod. The upper area ofl thev` plate IIlbetween the flanges I4 is punched and stamped to formy supporting and retaining elements which include anupper shank portion I6, a lower shank portion I8, a semi-cup-shaped retaining element 2l! integral with the shank I6 and a semi-cup-shaped member 22 integral with the shank I8. `These shank and cup elements when stamped leave perforationsl24and 26, in"the.ba`se plate I and a cross bai-'23' which supports them. The shank portions I and I8'are part'cylirldlfical in cross section and since they are lformed integrally with the relatively flat cross bar 28 and normal thereto an extremely rigid 'joint-between: them is formed. These elements maybe formed by. conventional punching anddie stamping operations.

` It should be noted that the' cross bar 28 is ,not perfectly flat, `butfthat it bends slightly to the rear as may be seen in dotted lines in Fig. 4. The reason for this is to provide a more rigid support for the shanks than a perfectly flat crossbar could provide, and also. to hold the. radius between the shanks and the. cross bar well to the rear and clear of theedges of the curtain rod slots. If this radius is more'io'rward, lthere is a chance that the edge of the'lcurtain rod slot would tend to wedge. in the ang-leformed between the curved partv of the shank in the area of-the. joint and theplaneof the base plate. I0.

Figs.- l and 2 how carriers of my invention mounted onl a, curtain f rod having telescoping sections 32 and 34.V It willbe seen that the carriers are supported in a rear slot 36 partlyjshown dotted lingala Fie.; 2 ci thecurtan Yrbd with the shankliterins-the-prinipal part 0f the weight andV with Vsem---iirulfn' cups 20 and 22 retaining the'carrierwithin' said slot 35 by overlapping the edges on the inside of-the slot 36. It will also'be seen that the surface. of'contact of the shank I8 resting on thev SuPpQrtinggedge of the curtain rod slot 36is radial inshape. and therefore will slide more'ea'silyand more noiselessly along the rod.

As may be seen in Fig. 4, there is a substantial gap between the shanks lland I8 and the cups and 22 wherein drawstrings (not-shown) may pass without becoming jammed; The shape of the cups 20 and 22' being rounded further promotes passage of the` carrier over random deformities in the shape of the rod and the step caused by theinner rod- 32' in telescoping relation with rod -34.- It will be noted that theidler carriers may tilt as they` are drawn alongthe rod, but thatl thesemi-cup-sha-pe of the retaining elements ensures a rounded surface of contact with the rod regardless ofany normally encountered degregoftiltf- The master carriers of my invention include a left master carrier- 40 and a right master carrier 42. This terminology-is employed merely for the convenience of; distinguishing carrier 4l) from carrierl 42 as they` are'normally vused inv the industry. It will be seen, however, that the positicning of these carriers may be reversed merely by re-positioning the arms presently to be described. The main bodies of the master carriers 40 and 52 are identical and therefore they will be described together using the same reference numerals. In fact, the principal dierence between the master carriers 40 and 42 is that the left carrier has an arm 44 in the same plane as the base plate of the carrier, while the right carrier A2 has a forwardly extending bottom flange plate 4G which passes underneath the curtain rod and supports an overlap arm 48 in a plane forward of the base plate. The arms 44 and Q8 are adapted to bring the inner leading edges of two curtains into overlapping relationship when the master carriers are brought together in the rod by drawstrings.

rIhe rod engaging and supporting arrangement for the master carriers comprises a base plate 50 perforated in its upper margin to provide two slots 52 and an upstanding arm 5d therebetween. In its lower margin the plate 5B is stamped to provide a slot 56 and a rearwardly extending hook 58 formed from the metal formerly in the slot 56. These latter mentioned elements may be employed in securing a drawstring to the master carrier bypassing a drawstring through one slot 52 from the forward side of the plate. then passingr the drawstring down and around the hook 58, and thereafter returning it up and forward through the other slot 52.

In the upper areal at'each end of the plate 5B, two sets of supporting and retaining elements are formed by conventional` die stamping in a manner similar to the formation of shanks It and I8 described above. Shanks 68 andv 62 extend forwardv andV are integral at their bases with a supporting crossbar E3 which remains between them. The shanks BD and 62 have an additional section of metal at each of their ends and this latter section is b ent into a plane essentially parallel to the plane of plate 5B to form retaining elements 68 and A,bent forward at each end to form slrigrunnersV '18.A When these supporting andretaining elements are formed, perforations 12 remain in plate 5D.

With particular reference to Figs. 8 and l2 it will be seenV that the shanks 6l) and 62 are slightly curved in cross section. This curve of shanks 69 and 62 is not as pronounced as that of shanks i6 and i8v of the4 idler carriers, but they are curved essentially for the same'purposes of promoting smooth and silent sliding of the master carriers in the slot 3S. The reason for the less pronounced curve is that the mastercarriers, being supported in two places, cannot rock while being drawn, as the idler carriers do when they are drawn.

The master carriers are provided with rearwardly extending flanges 'I4 at each end of plate 50, the flanges I4 are constructed similarly to the flanges I4 of the idler carrier described above and serve the same purposes.v

With particular reference to Figs. 7 and l0` it will be seen that the; cross bars 83 rather than lying directly in the plane of the plate 5I) bend slightly to the rear thereof' in a manner similar to the cross bar 28 of the, idler carrier described above. The reasonsfor this slight rearward bend are to linsure a4 smooth sliding contact between the weight-supporting shanks 62 andthe, lower edge of slot 35 of the curtain rod, and to increase the strength of the support connection.

Withreference to Figs. 9 and 11 it will ybe seen that there is a substantial gap between Shanks 60 and B2 thereby providing additional space for drawstrings to pass within the curtain rod, free of the retaining elements. However, in order to keep the drawstring from coming so far back as to jam in the curtain rod slot in the area of the master carriers small humps 16 are provided in plate 5i! by indenting the said plate during the stamping operation.

The idler carrier of Figs. 3-5 and the master carriers of Figs. 6-12 to a certain extent embody essentially the same inventive concept; namely, that of providing rounded weight-bearing elements and curved retaining elements in a single piece, stamped sheet metal member. Furthermore the shanks 60 and 62 of the master carriers, and shanks I6 a nd I8 of the idler carriers are all curved in cross section and lie in a plane normal to their supporting bases. It was also seen that the cross bars 28 in the idler and 63 in the master recede slightly to the rear of the carrier base plate for the same reasons. The runners 10 of the master carriers, of course, are not formed in the semi-cup shape of elements and 22, but as was explained, the master carriers cannot rock because they are supported in the slots 36 in two places, and therefore the runners 10 need only be curved and need not be in the form of semi-cups as are elements 20 and 22.

In operation, however, the curved surfaces presented by my supporting and retaining elements promote smooth sliding, particularly over the steps formed by the telescoping curtain rods. Therefore, in the claims I intend the term carrier to include both idler carriers and master carriers.

Since certain minor changes in the preferred embodiment of my invention herein shown will be obvious to those skilled in the art, it is not intended to confine the invention to the precise form herein shown, but rather to limit it in terms of the appended claims.
